AlN Aluminium nitride powder

Q: Which ceramic powder should I choose to improve the conductivity of my material or resin?

The choice depends on the desired thermal performance for the resin or composite. Aluminium nitride (AlN) powders increase thermal conductivity up to 150 to 200 W/(m·K), but also provide effective electrical insulation. Boron nitride powders (h-BN) increase thermal conductivity up to 40 to 60 W/(m·K) and thermal stability up to 800–900°C in air, providing a balance between conductivity and ease of application. Alumina powders (Al₂O₃), which are more cost-effective, provide a more moderate conductivity of 20 to 35 W/(m·K). Final Advanced Materials recommends adjusting the particle size and the load level to optimise overall performance.

We offer a range of high purity aluminium nitride powders. The thermal and electrical properties of these powders are particularly appreciated in the semiconductor and electronics industry. Since the powders have not undergone any surface treatment, they must not be brought into contact with air or moisture before being used.
